I am trying to run that script from my browser and all that comes up is a blank page. No posts are removed.

I switched db's last night and uiploaded all the old info - does that matter?

Do you have the expire date set on each forum? This is the setting when you create/edit a forum. It will only delete posts that are older than whatever you set here.

I have some as short as 3 days and there are posts 2 months old in there.

I used to run the perl doexpire.pl with no problem from the browser.
